PE vacuum anti-corrosion thermal insulation pipe production line (φ90-φ2000), combined with years of manufacturing experience, is our new pipe production line that is researched, developed and improved with introduction of foreign pipe extruding technology. Consisting of extruding, mould, vacuum sizing, cooling, traction, cutting and discharge equipment, this unit has features of high automation and output, stable property, and long service life etc. Compared with pipe produced by internal pressure method, it makes great improvement in smoothness, bearing capacity, output and piping speed, and currently has become the most advanced and excellent anti-corrosion thermal insulation pipe production
